1.1 This test method covers two laboratory procedures for determining the extrusion rate and application life (or “pot life”) of elastomeric chemically curing sealants for use in building construction.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.

1.3 There is no known ISO equivalent to this test method.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The results obtained by this test method are simply a measure of the time required to extrude a known volume of sealant through a known orifice under a predetermined pressure.

4.2 This test method is not considered a measure of cure rate.
